| Abstract:In order to effectively realize the precision measurement of actual air flow condition of the same section when using multisensor
system in afterburner test. The method eliminates suspicious data first based on Grubbs, and then employs an adaptive weighted
fusion estimated algorithm of multi-sensor to fuse effective data. A comparison between the effect of new multi-sensor fusion method and
arithmetic mean value method was conducted. The comparison results reveal that new multi-sensor fusion method have obvious advantage
on mean square deviation over arithmetic mean value method. Therefore, new multi-sensor fusion method has higher test accuracy and
reliability. |
